"At this point in Jessica's career, the record label dictated the length of her hair. It used to drive us crazy because a lot of her fashion choices, like this one, called for short looks, and I wasn't allowed to cut her long hair," says Ken Paves. "This night, she wore a 15-inch hair piece, and everyone was asking if she chopped her hair off. I told her to keep it to herself, but of course she told everyone, 'It's a wig!'"

"Jessica's gold dress was something you'd expect to see at the Oscars—totally glamorous. I wanted to balance it out with a soft style so she didn't look too mature or stuffy," Paves says. To create height in the front, he sprayed her roots with dry shampoo (he swears by Psssssst!, which only costs $6) and brushed them upward until her hair was sticking straight up. "It's like starching a shirt," he says about the technique.

"Jessica was wearing her hair down for her performance later that night, so we wanted to preserve her hair's texture to make the transition into that style as easy as possible. I used a 3/4 inch curling iron to create kinks and gathered them into a low side ponytail, leaving wisps and flyaways so the final product was a tad bit undone," Paves says.

"Jessica's natural hair is fine and straight, so she usually has extensions glued in to add texture and volume," Paves says. "This was a 10-minute hairstyle: we wanted her to look effortless and understated. I had her air-dry her hair, I used a drop or two of shine serum, ran it through her hair, then blasted it with a blow dryer." To create the separated curls, Paves twisted sections of her hair around his fingers and sprayed it with hair spray to keep it in place.

"I wanted to get away from her trademark wavy hair for this event," Paves says. "I pulled front side sections of her hair into a small ponytail at her nape, hiding it with the rest of her hair, which kept the sides smooth and behind the ears. Her hair was wavy from an earlier event that day, so I flat-ironed it (spraying it first with Biolage Thermal Setting Spray), applied shine serum, and added a little hair spray to set it."

"I had just cut her hair that morning into a bob! I applied shine serum into her damp hair and used a Mason Pearson brush to blow it dry, drying it forward from the back of the head. This keeps a bob smooth against the head," says Paves. "For the crown and front, I brushed it from side to side—this gives a bit of bend on the ends so the bob isn't too round."

"Here, I wanted her to look like a '60s-era actress, like Sophia Loren when she would put up her hair to take a bath. Jessica wore her hair down for the show, so I used hair pins to loosely hold it up. I love the way it looks with the collar on her jacket," says Paves.
